'fication.

This invention relates to new and useful improvements in tolling apparatuses. V

It is customary for the, miller to receive, as toll, a portion of the grain ground for the customer. This invention has to do with means for automatically taking the mi-llers toll and also the segregation of different 'kinds or qualities of grain.

The ObJQCt of the invention' is to utilize the flow of the grain to operate means to set the apparatus in motion and also to manip- 'ulate by theflow ofthe grain, means for causing the discharge of the grain into a segam, whereby each kind or qualityof' grain selects it own bin.

A further object is to divide the grain so that the toll is carried to the millers bin and the customers portion is carried to the grinding mill. Another object is to employ the flow of the grainto stop the operation of the apparatus.

Anapparatus designed to carry out the invention will be. hereinafter described together withother features of the invention. The inventionwill be more readily understood from a reading of the followingspecification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Fig. 1 is aside elevation of an apparatus embodying the invention, portions being illustrated in section to show interior parts,

Fig. 2 is a detail of the grain bin valve mechanism,

Fig. 3 is a side elevation of the hoppers and component parts,

Fig. 4; is a side elevation of the grinding I mill, and

Fig. 5 is a plan View of the elevatordriving means.

In the drawings the numeral 10 designates a base on which is an upright frame comprising, studs 11 having across beam '12 at their tops. A pair of feed hoppers 13 and 14' respectively, are suitably mounted on hangers 15 and 15"seeured on the beam 12.

. The hopper 13 has a depending spout 13',

while the hopper 14 has a similar spout 1 1. The spouts are inclined forwardly from the hoppers and are mounted on braces 16 fastened to the studs. The lower ends of the spouts are positioned over a receiving hopper 17 held between the studs by braces 18. The hopper 17 is mounted at the upper end of a vertical chute 19.

The chute has its lower end discharging into the boots 20 and 21 respectively of a toll elevator 23 and mill elevator 24 diverging from each other. The boots areseparated by an upstanding deflector partition 22 located so as to deflect the falling grain into the boots. It will be seen that if the deflector is located centrally of the chute, the grain willbe evenly divided between the two boots and consequently the location of the deflector controls the division of the grain. I V

In the toll' elevator 23 an endless bucket conveyer 20 is disposed and a similar eonveyer 21' is arranged in the mill elevator 24. The conveyers have their lower ends passing around pulleys 25. The upper end of the conveyer 21 passes around a pulley '26- moun-ted on a shaft 27 while the upper up into the lower end of the spout, centrally thereof, and separates the bins. A valve 29 is hinged'along the upper edge of the partition andis adapted to have its upper edge rest against either side wall of the spout, so as to obstruct the passage of the grain to one bin and deflect it into the other bin.

The valve has a horizontal shaft 29 extending rearwardly from the spout and pro vided with a bevel gear 32 on its end, which meshes with a bevel gear 33 mounted on a shifting shaft 34 carried by the studs, see Figs, 2 and 3.

In the spouts 13 and 14 gates. 35 extend from shafts 36 so as to project transversely of the spout and when swung downward, to rock said shafts 36; The shafts extend through the sides of the spouts and each has a depending lever 37 fixed on its outer end. A connection 38 extends from'the lower end of each lever. A pair of diametrically opposite arms 39 are provided on the shaft 34. The upper end of one of these arms receives the end of the connection 38 from the spout 14'; while the lower end of the other arm is attached to the connection 39 of the spout The gates arearranged so that when one is obstructing the passage of grain through its spout, the other is swung down and will be swung upward, whenthe first named gate is depressed.

It will be seen that the depression of the gate in the spout 13 will rock the shaft 34 in an opposite direction to the direction in which it is rocked by the depression of the gate in the spout 14. Consequently when the gate in the spout 13 is depressed by the grain, the shaft 34 is rocked so as to rotate the shaft 29 and swing the valve 29 to the left (Fig. 1), thus deflecting the grain into the bin 31. When the gate in the spout 14 is depressed the shafts 34 and 29 are rocked in the opposite direction and the valve 29 swung to the right (Fig. 1) so as to deflect the grain into the bin 30.

A spout 40 depends from the upper end of the elevator 24 into a hopper 41 mounted on the upper end of a vertical chute 42 mounted in a grinding mill 43, which latter may be of any suitable construction. Anelectric motor 44 is mounted adjacent the mill and has a pulley 45 on its armature shaft which drives a belt 46. The belt drives a pulley 47 mounted on the shaft 48 of the mill. The shaft 48 extends through the mill and has asprocket wheel 50 fastened on its opposite end. The wheel 50 drives a sprocket wheel 52 by means of a sprocket chain 51. The sprocket wheel 52 is fastened on the shaft 27 The parts are operated so as to operate the conveyer 21 to elevate the grain from its boot 7 21 as is indicated by the arrows.

or driving the shaft 27 of the conveyer 20 in reverse dlrection to the shaft 2'7,

bevel gear 53 is fastened'on the shaft 27 A shaft 55 is supported in boxes on the studs.

A bevel gear 54 mounted on the right hand end of this shaft is driven by the gear 53. A

bevel gear 56 mounted on the left hand end of the shaft meshes with a bevel gear 57 mounted on the shaft 2%, sons to revolve (he latterin a reverse direction to the shaft 27 Que of the featuresof the invention is to utilize the flow of the grain to start and stop the motor 44. The electrical circuit to the arm 60 is swung by a flap 62 hinged in the chute and normally extending horizontally across the same, in which position the arm 60 is at the lower end of its segment and the circuit is open. When the flap is depressed by the grain flowing down the chute 19, the arm is swung and the circuit to the motor is closed. p r

The rheostat 61 is located on the chute 42 and has its arm 61' connected with a flap 63 in the chute. The reason for the second rheostat is to keep the circuit closed and the mill running after the grain ceases flowing through the chute 19 and until it ceases to flow down the chute 42. Each arm 60 and 61 has a lever 63 attached to one end of a coiled spring 64 having its opposite end suitably supported. lVhen a flap is depressed he lever is. swung by its arm and the spring extended; thus when the grain ceases to flow past the flap, the spring returns the parts to their normal position.

The apparatus is operated as follows:

The customer selects the feed hopper which is marked to receive the particular quality, color or kind of grain he has to be ground. For instance the hopper 13 may be forwhite corn and the hopper 14 for yellow corn. lVe suppose the customer has .white corn so he dumps the same into the hopper 13. The grain passes down the spout 13 and depresses the gate 35, whereby the lever 37 attached thereto is swung and the shaft 34 rocked, by its arm 39 which is swung rearward, thus swinging the valve 29 to the left (Fig. 1) and closing the bin 30.

The grain passes down the spout 13. into the hopper 17 and down through the chute 19.. As the grain passes down the chute 19 the flap 62 is depressed and the arm 6O of the rheostat swung upward. This closes the circuit to the motor over the wires A, B and C and starts the motor. The motor drives the mill 47 and revolves the shaft 48 by the belt 46." The shaft 48 drives the chain 51 which revolves the shaft 27 and also the shaft 21 by the countershaft 55 and its gears. The shafts 2'7 and 27 being driven .in opposite directions cause both conveyors boot 21 to be conveyed to the mill 43. The

grain received in the boot 20 is elevated by the conveyor 20 and discharged into the I spout 28 from which it is discharged into the bin 31.

.he grain received is in the boot 21 elevated by the conveyer 21' and discharged from the spout 40 into the hopper 41, from which it passes down through the chute 42. As the grain flows through the chute 42 it depresses the flap 62; thus operating the rheostat 61 to clo e the circuit to the motor over the wires A, B, B, G and C. After the grain ceases to flow past the flap 62, the spring of the arm 60 returns the arm, swings the flap up and opens the circuit at this point. The motor continues to operate until the grain ceases flowing over the flap 62, at which time the circuit is opened and the apparatus stopped as will be obvious.

It is pointed out that no attendant or operator is required with this apparatus. The operation is automatic after the customer selects th proper feed hopper.
